Vertical separation of generation from electricity retailing has often been required as a condition of electricity market liberalisation. A well-developed and liquid contracts market is similarly suggested as necessary to manage the resulting wholesale market risks which risks are further...

Seamus Hogan presented Vertical Integration and Market Power in Electricity Markets at an ISCR seminar in Wellington on 1 May 2007

There has recently been considerable discussion about the ability of inflation to facilitate the adjustment of prices and wages and thus enhance economic performance. The discussion centres on whether wages are downwardly rigid. Wages are said to be downwardly rigid if it is difficult for the...

This paper is part of a wider research programme using a dynamic-programming approach to modelling the choices about the amount of risk to take by batting and bowling teams in One Day International cricket. An important confounding variable in this analysis is the ground conditions (size of...

This paper derives a general sufficient condition for existence and uniqueness in continuous games using a variant of the contraction mapping theorem applied to mapping from a subset of the real line on to itself. We first prove this contraction mapping variant, and then show how the existence...

The fixed-price-offer (FPO) mechanism in <italic>Trade Me</italic> auctions allows sellers to make a take-it-or-leave-it offer at the conclusion of an unsuccessful auction. Weinvestigate the effects of the FPO option on strategies and outcomes in independent-value auctions. The FPO option induces some bidders...

This article is concerned with models in which an agent faces a lottery with <italic>j</italic> other agents for a prize, so that the probability of winning the prize is 1/(<italic>j</italic> + 1), and where <italic>j</italic> is stochastic. After describing four different situations where such a lottery is present, we construct the expected...

In a standard English auction in which bidders’ valuations are independently drawn from a common distribution, a standard regularity condition is that the survivor function of the distribution be log concave. In an auction where the seller sets a fixed price, the equivalent condition requires...

The Fixed Price Offer (FPO) mechanism in Trade Me auctions allows sellers to make a take-it-or-leave-it offer at the conclusion of an unsuccessful auction. We investigate the effects of the FPO option on strategies and outcomes in independent-value auctions. The FPO option induces some bidders...

This paper discusses the desirability of government-legislated job security. Job security may be beneficial to employed workers, but it can also impose a cost on unemployed workers by lowering labour market turnover and thereby increasing the average duration of unemployment spells. This...
